Installing Mavericks as VirtualBox Guest

Posted at December 14, 2013.

Recently, I set out to get OS X 10.9 running as VirtualBox Guest, with Mavericks as Host. This should be easy enough, right? Just download the Mavericks Installer from the AppStore, get the Image from inside the App Package, as you would do to get a bootable USB Stick. Done!

It turns out that Apple started using strange Aliases in their Install Image with Mountain Lion. You have to do some moving around to get an ISO you can plug into VirtualBox.

If you got the Mavericks Installer in /Applications, run this script to get a bootable ISO on your Desktop.
